Condition: 100% Brand New
Item Type: Water Quality Tester
Material: Titanium Bar+ABS
Voltage: 220V
Weight: Approx. 178g / 6.3oz

Description:
This instrument has electrolytic rods with positive and negative poles (one is an iron rod and the other is an aluminum rod), that is, two electrodes introduced as an electric field. After the electrolyzer is energized, under the action of the current, the positive Fe3+ ions are dissolved, and they will combine with the negative OH- ions in the water to form water-insoluble Fe(OH)3 particles. These particles affect the colloidal particles in the water. The aggregation and adsorption activity is very strong, and thus form the adsorption and aggregation process of organic or inorganic substances in water.
At the same time, due to the action of electric current, metal particles such as manganese, potassium, cobalt, etc. originally dissolved in water are reduced and gradually aggregated to form metal clusters. Different metal ions have different colors, resulting in color separation.
Instructions:
1. Prepare test water—take two white glass cups with a capacity of 100-150ml, one cup for tap water and the other for RO machine water, and discharge them on the table.
2. Preparing for inspection—Put the electrolyzer flat on the glass and plug in the 220V power supply.
3. Inspection—Press the power switch button on the electrolyzer to the ON position to start inspection.
Usually the inspection time is 30 seconds. At the end, first press the power switch to the OFF position, and finally take out the electrolyzer.
Color Display Description:
Yellow: Dissolved acid, silicon compounds, organic minerals, molybdenum, silicon, fluoride, and other organic substances
Green: Arsenic (arsenic), lead, copper, sodium
Blue: Carcinogens, organic phosphorus, etc. (chemical fertilizers, detergents and pesticides)
Red: Iron and rust
White: Lead, zinc, inorganic salt dirt
Black: Heavy metals (zinc, lead, copper, chromium, manganese, cadmium)
Standards for Measuring Water Quality :
1. It does not contain any substances that are harmful to human body and have peculiar smell (especially heavy metals and organics)
2. The hardness of water is moderate, usually between 50-200mg/L (calculated as calcium carbonate)
3. The PH value is weakly alkaline (7.0-8.0)
4. The content and proportion of trace elements and minerals in the water are moderate, similar to normal liquids
5. The content of dissolved oxygen and carbon dioxide in water is moderate (dissolved oxygen in water ≥ 6-7mg/L)
6. Water has strong nutritional and physiological functions (including dissolving power, osmotic power, diffusing power, metabolic power, emulsifying power, washing power, etc.)

Package List:
1 x Water Quality Tester
2 x Iron Rod
2 x Aluminum Rod

Note:
1. After turning on the power, do not hold your hands on the electrodes
2. Do not put your fingers in the test water
3. Do not let children play with the electrolyzer.
4. After the electrolyzer is used up, wipe the electrode with a dry cloth, and wipe the water on the iron pole with a fine gauze cloth, and keep it properly.
5. If the electrode corrodes after using for a period of time, please sand it lightly with fine sandpaper, and apply a little food oil after polishing to prevent rust.
6. Dear customer, please rest assured to buy without worrying about the plug adaption. We will provide an adapter for you according to different country standard for ensuring its normal use.
